Hello all,
I came across the following issue and I would appreciate any help or recommendations.
I have a rectangular shaped industrial oven which has some maintenance doors on the side, around every 50 to 60 ft. There are cases where these doors may be open either accidentally or for any other reason.
The oven operates at 480F. The sprinkler ceiling system right above, some 15 ft higher from top of oven, is to cover a much more wider area with standard 165F sprinklers. The ones above these open doors would need of course to be of higher temp. classification. NFPA 13 commentary says the following
How would you interpret the term "immediately above equipment"? Personally I wouldn't trust having only one or two heads right above these doors. How large would that area with high or ultra high temp. sprinklers normally have to be?
The other question here is what kind of temperature class would the heads need to be?
Any comments are welcome. Thank you.
